Biometric security systems that utilize fingerprints, electroencephalogram (EEG), and face recognitions are vulnerable to cyberattacks. With personal and confidential information at stake, it is vital that these systems are complex and able to resist data breakage. One form of protection is applying machine learning to these systems.

Spatial changes during building construction usually manifest as deviations between the as-designed model and the as-built conditions. These deviations can lead to errors that result in delays and additional costs. Project engineers often spend significant time, money, and resources to manually track and analyze changes between the as-designed mode...

Deep convolutional neural networks (CNN) are useful in a variety of applications ranging from computer vision to signal processing. There is increasing interest in applying CNN to biomedical image analysis, but success is impeded by the lack of large annotated datasets in biomedical imaging. Expert annotation is tedious, time consuming and expensiv...

Haptic displays have promising applications in assistive devices for the visually impaired. However, current versions of this technology remain confined to low resolution tactile replications of images, and thus provide limited usefulness. Conventional haptic displays use motors or electrodes to convert images to touch, using an interface that is a...

Antibiotic resistance has become a significant public health threat. It causes billions of healthcare-related costs as well as 2 million hospitalizations and 23,000 deaths annually in the US alone. Clinical treatment of bacterial infections, especially in acute cases of sepsis, requires multiple steps, including antibiotic susceptibility testing (A...

Electromagnetic Band-Gaps (EBGs) have been extensively used in low-profile antenna designs because of their in-phase reflection characteristics in certain frequency band(s). EBGs have also been used as attractive ground planes and in checkerboard surface variations.
The incident waves on checkerboard patches induce current densities whose amplitud...

High Impedance Surfaces (HIS) are one of the breakthroughs that emerged in the modern antenna design area in 1999. HISs are ideal candidates as antenna ground planes because of their near perfect magnetic ground conductor (PMC) behavior at particular ranges. However, current rectangular designs have a limited performance and lack efficiency in the ...

Pervasive Brain-Mobile Interfacing (BMoI) is a new trend that has significantly increased within this decade through the creation of wearable dry contact electroencephalogram (EEG) sensors. Unfortunately, current commercially wearable brain sensors have low accuracy, power limitations and computational restraint based from mobile devices. These lim...

In standard medical practice, the patient and their medical image data are decoupled after imaging. Image visualization is primarily confined to screens that are not registered with respect to the patient's body. This is cumbersome and requires more time for healthcare providers to orient the images relevant to the patient. It would be ideal to hav...

Compressed Sensing (CS) technologies are becoming increasingly important in the signal processing field. Sensors in CS do not output the signal of interest, but instead, output a vector of measurement composed of mixtures of the signal’s components. This compressively sensed data can be reconstructed, and the results may be used for purposes ...
